Wireless LAN products sold in the U.S. must be certified by the Federal Communications Commission (FCC). The certification process requires that the manufacturer submit detailed information about a product including external and internal construction detail photos and test reports.
The FCC website has search tools that can find a product by its FCC ID (usually found on the serial number label of the product) and also find manufacturers' three-character 'Grantee Code' that is helpful for general product searches.
